Now Amy sets the charge to 1e, the mass to 1me, the speed to 3.00 106 m/s, and varies the magnetic field. With respect to the path of the charged particle, what can she say she observes? "As the magnetic field increases, the radius first increases, then decreases." "As the magnetic field increases, the radius stays constant." "As the magnetic field increases, the radius decreases." "As the magnetic field increases, the radius first stays constant, then increases
